Application filed April 23,1920a Serial No. 376,059.

To all wi l-0m it may concern Be it known thatl, ELLIS R, BROOK, a

citizen of the United States, and resident of Bamberg, in the county ofBamberg and State of South Carolina, have invented certain new anduseful Improvements in Thread-Board Cleaners for Spinning-Mia chines, ofwhich the following is a specification. v

This invention relates to means for clean-,

ingthe threadboard of spinning machines I and is in the nature ofan'attachment which ing the device on spinningmachines and its Ycontinuously back and; forth over and. in

' contact with the surface. of the guide board.

and the hingedthread guide extensions from one'end of the guide boardto. the other across the machine, collecting and removlng the fine lintand dust which tends to-collectthere. The'purpose of the invention is'tosimplify and improve the construction whereby the desired result ofcleaningis secured'moreperfectly while at the same time thecost andtrouble of manufacture, thework of installliability to get out of orderare'reduced.

"The novel features of construction will be apparent from the'followingdescription and. claims taken in connection'with' the draw-' ings. V

- It has not been deemednecessary to show in the drawings many partsofthe spinning machine towhich my invention is applied since thestructure, arrangement and opera-" tion of suchmachines are wellknowntand will beunderstood and itis necessary there fore to show onlyso much of the "old machine as will make clearhowmy' invention 7 isapplied to it. In the'drjawings10"repre sents the thread board' whichcarries along one edge the hinged member's 1l:'-p1-ovided of the threadboard and thread guides. of a known form of Patented Mar; 1, 192 1.,

The pulley: 19 is.driven throng-ha; shaft 20 and bevel: gears. 21,? 22 anda beltwheel 23which may be connected by belt 24 to "one of the rotating shafts oi thespinning 'machine so as to constantly drive the pulley 19; Adjacent thedriven. pul1ey 19 there are two loose pulleys25 which bear on theo'uter"margins of the belt or cord abringing' them closer together than theyWould'beif drawn straight from the'pulleyand a pair of simi lar freepulleysareplaced-adja'cent the loose pulley for the same purpose on -theother;

sideof the 'machine.*-A housing'27lpriefera v.

V Fig.2 is a vertical section taken in the tially rectangular in section-lwilth a? 'slot' inthis hOuSinganclis-thus largely protected from fiberand dirt, This'housing occupies Opening '28. in the -top and the cordonbelt p Z 17 passes long tudinally across the machine' Fig. 3 1s across-section on the line 3-1-3- portion and is'thus belowthelanushimechathe housing-27 so as to slide freelylongilcord- 17 passes"within this housing 29 im tudinally therein andisrigidly secured tovthe-solid member of the brush 'l 5- 'by' suitable means such as: the I-fpOSt30f 'The', belt or;

a' position between th'eisections of bristlef extending downward fromthe brush top brush, which slot serves as a guide.

serves as one part of the clamping means for connecting the cleaningdevice orbrush 15 to the belt or'cord. On the upper face of the brush 15there are two-posts 31, 32 having mounted therein ashaft 33 which isrotata- 'ble and which carries two cams 34 and 35 rigidly'secured to itso as to turn with it. Each cam has rotary connection with thecircularly bent end of the movable clamping strip or member36 and thatclampingmember extends from the cam downwardly at an angle-through aslot 37 in the top of lthe e lower end of the clamping arm 36 extendsthrough the slot 28 in the top of the housing 27 and down to a pointjust above the cord or belt and is there bent toform a downwardly facingbearing surface 38 adapted to bear downwardly-pressing the cord againstthe inner. lower face of the housing 29 thus clamping itto the brushorcleaning device. Itwillbe observed that" there is a movable clamping armfor each side ofthe cord or belt and that they are inclinedat differentangles.- The camecc'entrics on which these movable. clamping arms aremounted are so arrangedthat when the greater. diameter of the eccentricis approximately in line and on the sameiside as theclampingarm in onecas'egthat; arm willkbe pressed down into clamping position while theeccentric for the other arm will at that timeihave'. its

:greatest diameter out of lineIwith its clamp ingmember and thusthatmember will be raised from clamping position. Itzis of coursenecessary in moving? the brush or cleaning, device from. one side of themachine ,tothe other that it shall be clampedto oneside of the cord andto make it automatically stop andstart areverse movement backto theotherside of the machine, itis necessary to release the clamp on oneside and apply thatontheother side. In my device this is done by meansof the'extensions 39, 40 rig-v idly secured to the eccentricsor theshaft;

, and so arranged thatthe'one on the forward side of movement'will be insubstantially a horizontal position andwill strike aninclined abutment41' as the brush reaches one end of the threadboard and this abutmentwillraise the arm 39 turning-the two eccen-' 'trics releasing one clampand applying the other automatically. I

have shown this'abutment for-effecting the 'reverse in the clamps onlyat the driving end "ofthe thread board, but it will be understood thatthere is a similar arrangement at In- 7 the drawings I the other end.

Having thus described my invention what is claimed asnew and desired tobe secured by Letters Patent is r {1.- In a cleaning device boardsofaspinning machines the: combination with an endless belt extendingover said,

thread board from one side of themachine to for at." thread the other,means i for driving said belt, a I

as to disengage one portion of the belt and engage the other portion forthe reverse movement of the cleaning device.

5. In a cleaning device for the thread boards of spinning machines thecombination with an endless belt extending over and close to said threadboard from one end to the other, means for driving said belt, a cleaningdevice over said belt in the form of a brush with bristles extendingdownwardly into contact with the thread board on both sides of saidbelt, means for alternately clamping said brush to opposite sides ofsaid belt to cause its reciprocation over the thread board and automaticmeans for shifting the clamp at the end of the board tocausereversemovement. 6. In a cleaning device for the threa boards ofspinning machines the combinae tion with an endless belt extending overand close to said thread board from one end to the other, means fordriving said belt, a
